> Right now there is a mixture of different kinds of loops within aggregate functions.
Although performance is not the main goal at the moment, we should focus on performant execution
especially in this runtime functions.
> e.g. {{DataSetTumbleCountWindowAggReduceGroupFunction}}
> We should replace loops, maps etc. by primitive while loops.
